초등학교 6학년을 대상으로 6회 총 120분 동안 1996을 활용해서 1에서 100까지 수를 만들게 하는 활동을 한 결과를 제시하고 분석하였다. 이 퍼즐 과제 활동은 아이들의 수학적 사고를 많이 향상시켰으며, 수학적 성향을 강화시켰다. 특히, 이 과제에서 아이들은 협동의 이점을 알게 되었고 수학적 의사소통의 중요성도 경험하는 계기가 되었다. 무엇보다도 지수, 제곱근, 가우스 함수의 아이디어가 먼저 제시되고, 후속학습이 일어났다. 계산기가 어떻게 활용되어야 하는지에 대한 아이디어도 제공했다.

본 논문에서 제안하는 수학학습 시스템은 구성주의 원리에 입각하여 학습자 중심의 다양한 학습 방법을 통해 자발적이고 협동적인 학습이 가능하도록 설계하였다. 특히 XML 문서를 통해 수학과 교수학습 지도안의 표준을 지향하며 본 시스템을 통해 데이터가 공유될 수 있게 하였다. 본 시스템의 구성요소는 게임, 진단학습, Q/A, 그룹학습으로 구성되고 이들간의 상호 유기적인 관계를 구성하고 있다. 따라서, 본 시스템은 학습자가 스스로 학습할 수 있게 도와주는 다양한 학습방법에 의한 수학학습이 이루어질 수 있다.

The main game architectures for multiplayer online games are the traditional client-server architectures, multi-server architectures and P2P(peer-to-peer) architectures. P2P architectures, due to their distributed and collaborative nature, have low infrastructure costs and can achieve high scalability as well as fast response time by creating direct connections between players. However, P2P architectures face many challenges. Distributing a game among peers makes maintaining control over the game more complex. These architectures also tend to be vulnerable to churn and cheating. Providing consistency control in P2P systems is also more difficult since conflicting updates might be executed at different sites resulting in inconsistency. In order to avoid or correct inconsistencies, most multiplayer games use a primary-copy replication approach where any update to the object has to be first performed on the primary copy. This paper presents the primary-copy model with the update dissemination mechanism that provides consistency control over an object in P2P architectures for multiplayer online games. The performance for this model is evaluated through simulation experiments and analysis.

Teaching and learning through games which arouses interest in learning not only lessens a burden of a learner but also labors for Academic Achievement. and for the sake of enhancing convergence of thinking and problem solving abilities as well as raising interest and understanding in science and technology, Steam teaching which is mainly made of research and experimental activities is emphasized on. This paper which makes use of crayon physics has developed Steam program it was mainly applied to science for the first year of junior high school [strength and motion] which for learners of each team is made of four steps eight time in total. At each step learners can understand principle of strength and motion, especially at the step of finding principle of science through games can personally solve the game in cooperation with the leaners of a team and find principle of strength and motion which is to be applied to solving the game. By personally designing and making new games learners can enhance the ability of convergence of thinking. It is expected that the program developed in this paper can enhance imaginativeness of thinking and interest in science which lead to affirmative changes.

The purpose of Serious games in immersive Metaverse platform to provide users both fun and intriguing learning experiences. We proposes a serious game for self-trainable fire evacuation drill with collaboration among avatars synchronized with multiple trainees and optionally with real-time supervising placed at different remote physical locations. The proposed system architecture is composed of wearable motion sensors and a Head Mounted Display to synchronize each user's intended motions to her/his avatar activities in a cyberspace in Metaverse environment. The proposed system provides immersive as well as inexpensive environments for easy-to-use user interface for cyber experience-based fire evacuation training system. The proposed configuration of the user-avatar interface, the collaborative learning environment, and the evaluation system on the VR serious game are expected to be applied to other serious games. The game was implemented only for the predefined fire scenario for buildings, but the platform can extend its configuration for various disaster situations that may happen to the public.

Today, It has developed actively e-learning according to web without time and place which increase of PC user with super-highway information network and various up-to-date information rapid growth. It has to provide the chance to student which will be able to practice and to think free and originative under liberal learning environment that learner can compose knowledge through various thinking by themselves. From the present paper, I would design e-learning system using TGT model of cooperative e-learning system that more effective studying through advantage of e-learning studying. I look forward to helping improvement of student's real ability as embody competitive games method by TGT model's basic theory of web-based.

This study tried to look into various linguistic elements of MMORPG and suggested teaching methods to be applied in teaching and learning English. To support this idea, diverse attributes of CALL applications were investigated and suggested suitable position of MMORPG in technological stream of CALL. After that, focusing on 'Goonzu Global', the linguistic environment of MMORPG was considered. Based on aforementioned results, this study proposed an effective method to utilize MMORPG in teaching English adopting three teaching methods; collaborative method, task-based learning and problem-based learning.

What difference does the metaverse experience have from the real world? This study investigated the effect of space size and dialogue topic on metaverse user experience. The results from a 3(space size: reality vs. metaverse in an open room vs. metaverse in a closed room) x 2(dialogue topic: positive vs. negative) mixed factorial design experiment (N = 75) revealed statistically significant effects of space on responsiveness, and dialogue topic on closeness. This result implies that designing metaverse for non-immersive devices should include careful considerations regarding the characteristics of the user's real space.

As the growth of the live streaming service market is accelerating due to COVID-19, the number of downloads and reviews of live streaming mobile applications is also rapidly skyrocketing. This study is to research game streaming applications using Twitch reviews as database. A total of 8 topics are extracted through LDA topic modeling and 7 out of them are detected to be inconvenience factors. Then, to pinpoint the main inconvenience factors, co-occurrence analysis is used in order to find out main factors. Finally, based on previous studies, several solutions are provided, which can solve the inconvenience factors(advertisement, UI design, technology problems) as well as strengthening digital competitiveness. This study will serve as an opportunity to improve digital competitiveness not only for Twitch but also for other game live streaming service companies in the future.

본 논문에서는 중첩 된 WBAN(Wireless Body Area Network) 환경에서 비경쟁 전송구간의 신뢰성 있는 전송을 위해 한정된 자원(비경쟁 전송구간)을 각각의 WBAN에게 할당하는 방안을 제안한다. 이를 위해 협동적 게임 이론(cooperative game theory)을 바탕으로 한정된 자원(비경쟁 전송구간)을 효율적이고 공평하게 할당 할 수 있도록 내쉬중재(Nash arbitration) 기법을 통한 자원 할당 방안을 살펴본다. 내쉬중재 협상해법을 통해 WBAN 간 비경쟁 전송구간의 충돌 없이 신뢰성 있는 전송을 보장한다. 또한, 각 WBAN의 비경쟁 전송 구간 내의 디바이스 우선순위와 할당받은 timeslot의 개수를 고려하여 전략 선택에 따른 형평성과 각 WBAN이 비경쟁전송 구간 내에 요구하는 최소한의 timeslot을 보장한다.
